摘要：

The present study comprises the comparison of the electrochemical behavior of friction stir weld (FSW) joint and tungsten inert gas (TIG) weld joint of AA2014 using immersion test, potentiodynamic polarization test and electrochemical impedance spectroscopy (EIS). Weld thermal cycles and microhardness were correlated with corrosion behavior of the weld joints. TIG weld joint showed lower corrosion resistance than FSW joint. Heat affected zone was the most corrosion susceptible region in both type of weld joints. Optical microscopy, FESEM, TEM and XRD analysis were performed to discuss the corrosion behavior in light of the microstructure.
